论文摘要
使用最近提议的记忆量化基于与半群的进化的偏差，研究了称为量子半马科（QSM）过程的随机过程的非马克维亚性，该过程提供了对可划分和不可分割的通道的统一描述。证明这可以带出QSM过程的属性，即使在CP-划分方面也表现出记忆效应，这与较早的结果一致。还提供了半马尔可夫流程的非马克维亚性质的操作含义。
The non-Markovianity of the stochastic process called the quantum semi-Markov (QSM) process is studied using a recently proposed quantification of memory based on the deviation from semigroup evolution, that provides a unified description of divisible and indivisible channels. This is shown to bring out the property of QSM processes to exhibit memory effects even in the CP-divisible regime, in agreement with an earlier result. An operational meaning to the non-Markovian nature of semi-Markov processes is also provided.
